The first siege of Callao was a prolonged military blockade of the Real Felipe Fortress (as well as other fortresses) in Callao by the Liberating Expedition of Peru under the command of General José de San Martín in July 1821 which culminated in the capitulation of Marshal José de La Mar in September of the same year, with him switching sides from the Royalist side to the Patriot side.

The second siege of Callao was the longest lasting siege that occurred on the Pacific coast during the Spanish American wars of independence. The siege was carried out by the combined Gran Colombian and Peruvian independence forces against the royalist soldiers defending the Real Felipe Fortress in the port of Callao, who refused to surrender, and refused to accept the capitulation of the Battle of Ayacucho. The siege took place from December 5, 1824 to January 23, 1826, when the royalist stronghold was defeated, ending the Spanish Empire's presence in South America.

The third siege of Callao was a siege that took place in 1838 during the War of the Confederation between the United Restoration Army, supported by the Chilean army and the Peru–Bolivian Confederation. The confederates defeated the restorationist forces, who then retreated to Huacho due to the advance of the confederate army led by Andrés de Santa Cruz.

Callao is one of the seven districts of the Constitutional Province of Callao in the Callao Region, Peru. The Chillón River marks the district's northern border with Ventanilla. On the east, the Callao district is bordered by the Carmen de la Legua-Reynoso as well as the Lima Province's districts of San Martín de Porres and Lima. The Bellavista and the La Perla districts are located to the southeast, while La Punta borders the district on the west. The Pacific Ocean borders the province on the west and south. At 1956, it expanded to the north, encompassing latifunds, lands and estates that belonged to the San Martín de Porres District and the Carabayllo District. During this expansion, the Jorge Chávez International Airport is built.Since Jorge Chávez International Airport as well as Peru's main seaport are located in this district, Callao is the largest port of entry to Peru. The city of Callao forms a conurbation with Lima and thus, the district is economically, socially and culturally integrated with this city. (See: Lima and Callao Metropolitan Area).

The Spanish fleet bombarded the port of Callao (or El Callao), and eventually withdrew without any notable damage to the city structures, according to the Peruvian and American sources; or after having silenced almost all the guns of the coastal defenses, according to the Spanish accounts and French observers. This proved to be the final battle of the war between Spanish and Peruvian forces.
